我的代码：
int myswap(int &x, int &y);

int main()
{
int a,b;
scanf("%d%d",&a,&b);
myswap(&a,&b);
printf("%d %dn",a,b);
return 0;
}
int myswap(int *x, int *y)
{
int t;
t=*x;
*x=*y;
*y=t;
}

显示错误：
C:Users404NotFoundDesktopfaq666.c(6) : error C2143: syntax error : missing ')' before '&'
C:Users404NotFoundDesktopfaq666.c(6) : error C2143: syntax error : missing '{' before '&'
C:Users404NotFoundDesktopfaq666.c(6) : error C2059: syntax error : '&'
C:Users404NotFoundDesktopfaq666.c(6) : error C2059: syntax error : ')'
C:Users404NotFoundDesktopfaq666.c(12) : warning C4013: 'myswap' undefined; assuming extern returning int

这道题谁能帮我看一下

int myswap(int &x, int &y);
声明错了

int myswap(int &x, int &y);
改为
int myswap(int* x, int* y);

int myswap(int &x, int &y);

  貌似c++里这样玩

#include <stdio.h>

 
int myswap(int *x, int *y);

int main()
{
    int a,b;
    scanf("%d%d",&a,&b);
    myswap(&a,&b);
    printf("%d %d\nn",a,b);
    return 0;
}

int myswap(int *x, int *y)
{
    int t;
    t=*x;
    *x=*y;
    *y=t;
}
